65 DLI and lighting schedules

That is very very impressive

This monstrosity was also grown under autocobs…

That's probably mostly because either you give it less CO2 than it needs, or some other stressor. The plant easily surpasses and can get up to 100 DLI in some of the cutting-edge study papers I've read, with increases in dry mass up until that point as well! If you want, I can share the papers with you. It is by Bruce Bugbee and another Ph.D. student.

No it's not that, it's just that the leaves get bleached, I'm not really trying to do anything I just see that the plant is not responding well. to the light, leaves aren't looking happy. I'm always turning the light up and back down all day. Sometimes at night it's looks way too bright which is way I am constantly using a lux meter. the thing is that because I top everything so I end up with a canopy that I want to get at least 35DLI on, more if possible, but I'll have a foot of colas sticking above that wobbling around that that can get near 70 at the top so I am always manipulating everything all the time which is irrelevant in an even canopy grow. I am much happier with my grows since I cut my wattage down with the viparspectra.

@Frankthetank it's alive!

I bought the biggest light that fit my 4x4, 800W

It's plenty on auto strains that I can run 18-20 hours, but sativa that needs 13 hours of light to flip I've had to run it full.

If it's bleaching, then that is about the amount of red light on your lights. More red light means a greater inclination for the leaves and/or buds to become bleached. This is well-studied. Your nutrients are probably not enough for the flower as well, my friend. The higher the light, the higher the nutrients should be. This is also well-studied.

Just being curious… do you currently or have you grown before? It’s always interesting how folks put their prior experience to work with some of these newer techniques.

Of course, my friend. I'm just trying to take it to the next level.

Interesting I have noticed that I do not get nutrient burn even on the tips and I let the plug get up to 2800ppm! which is like 5.6EC! I have a UV light on but tbh, I don't think it does anything. The only red are a few diodes in the xs1500pro and the whites are 6500K and 4000K so that shouldn't be a problem I would think.
